Badly, unless you count the car. There's no railway station. More than half of working residents drive to work. More than a quarter don't travel at all and work from home. Midhurst is connected to the rest of the country mainly through its residents' car keys.
Midhurst was once a railway town, served by lines from Petersfield, Pulborough and Chichester. The last passenger trains ran in 1955, and today under 1% of commuters travel by train, which is about the share you'd expect for a town with no station at all. Buses have taken over what's left of public transport. There are 60 bus stops in the area, but only about 1% of commuters use the bus to get to work.
The way people actually get to work tells the real story. About 54% drive, about 28% work from home, about 9% walk and about 1% cycle. About 41% of households have two or more cars, while about 15% have none. For that last group, Midhurst is a very different town.
The Department for Transport's journey-time statistics are modelled averages for the whole area, not a route from any particular front door. They put the nearest town centre about 8 minutes away by car, 10 by bike, 13 by public transport and 14 on foot. Those figures are close together, because for most people the nearest town centre is Midhurst itself. The problems start when you need to go anywhere further.
A GP is about 10 minutes by car, 22 by public transport and 26 on foot. Hospital is where it gets serious: about 27 minutes by car and 52 by public transport. That's a long time on a bus with a broken wrist. A food shop is about 7 minutes whether you walk or drive, so the milk run is easy. The nearest cluster of employment is about 7 minutes by car and 29 by public transport. The public transport times date from 2019, and services have been cut in many places since then, so treat them with more caution than the car and walking times.
The buses are better than you might expect from a town where hardly anyone takes one. The stops with timetable data average 287 scheduled departures each on a weekday and about 15 an hour at peak, and 96% of them have some weekend service. A service that frequent ought to be used by more than about 1% of commuters. The buses run fine; most people have just stopped thinking of them as the way to get to work.
Superfast broadband reaches about 95% of the area, and no premises fall below the universal service minimum. Gigabit and ultrafast connections each reach about 2%. That's fine for the home workers who hold the town together during the week, and disappointing for anyone who assumed a place this well-off would have fibre by now.
Fourth- or fifth-generation mobile signal is available from at least one network across 100% of the area, and from all networks across about 98%. Your phone won't be the problem.
Every postcode in the area sits near or above 65 decibels of road noise, the level at which official noise mapping treats it as significant. The loudest band recorded reaches 75 decibels. That's what comes of a town built at a crossroads: the main roads run through the middle of it, not around it. There's no measurable rail noise, which follows from having no railway.
There are 3 public charge points in the area, with 5 connectors between them, and 1 of those is rapid. With only one rapid charger, charging an electric car here is something you plan for, and probably something you do on your own driveway.
Connectivity is Midhurst's weak spot. The roads, the buses and the broadband are all adequate, but the town has never got over losing its railway.
